SHADE-ROLLER.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed May 25,1907. Serial No. 375,688.

To all whom it may concern:

Be it known that I, CHARLES N. HINER, a citizen of the United States, residing at Bridgewater, in the county of Rockingham and State of Virginia, have invented a new and useful Shade-Roller, of which the following is a specification.

The invention relates to improvements in shade rollers. l

The object of the present invention is to improve the construction of shade rollers, more especially the means for holding a spring actuated shade roller at any adjustment, and to provide a simple, inexpensive and eflicient device adapted to be readily applied to spring actuated shade rollers of the ordinary construction, and capable of operating effectively when the shade is ar ranged either in a vertical, horizontal or inclined position to adapt it for use in photograph galleries and various other places. 7

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:-Figure 1 is alongitudinal sectional view of a portion of a window shade provided with a shade roller, constructed in accordance with this invention. Fig. 2 is a sectional view, taken substantially on the line x.t of Fig. 1. Fig. 3 is a detail sectional view of the clutch casing. Fig. 4 is a perspective view of the same. Fig. 5 is a detail perspective view of the journal to which the spring of the shade roller is connected. Fig. 6 is a sectional view similar to Fig. 2, the ball being out of engagement with the polygonal portion of the spring journal.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

1 designates a window shade, having a spring actuated shade roller 2, and provided at one end with a journal 3 to which an interiorly arranged coiled spring 4 of the usual construction is connected. The journal 3, which supports one end of the shade roller, is provided with an outer flattened portion 5, adapted to engage a bracket 6 of the ordinary construction, whereby the journal 3 is held stationary.

The journal 3 is provided with an intermediate p0- lygonal portion 7, and it has inner and outer bearing portions 8 and 9, located at the inner and outer faces of the polygonal portion 7. The polygonal portion 7, which is substantially rectangular, is arranged within acentral enlarged opening 10 of a cylindrical clutch casing 11, having a reduced bearing opening 12 at its inner face to it the inner rounded bearing portion 8 of the spring journal. The clutch casing is arranged within a metallic cap 13, which is fitted on the adjacent end of the shade roller and which is providedwith a central opening 14 at its outer end to fit the outer bearing portion 8 of the spring journal 3. The clutch casing is provided at its periphery with a plurality of transverse grooves 18, and the metallic cap is exteriorly grooved or depressed at 19 to engage it with the transverse grooves of the clutch casing, whereby the clutch casing is rigidly connected with the spring actuated shade roller, and is effectually prevented from rotating or turning independently of the metallic cap. The grooves or depressed portions 19 of the metallic cap extend to the inner edge of the cylindrical portion thereof and assist in interlocking the cap with the spring actuated roller.

The clutch casing is provided with an inclined or angularly arranged recess 15, communicating at its inner end with the enlarged opening and having an outer wall 16, extending inwardly towards the enlarged opening-and the polygonal portion 7 of the journal 3 for directing a ball 17 into engagement with the same. The ball is adapted to become wedged between the inner portion of the wall 16 and one of the faces of the polygonal portion 7, whereby the spring actuated shade roller is locked against rotary movement. When the shade roller is rotated by the spring or by an adjustment of the curtain, the ,ball is thrown to the outer end'of the angularly disposed recess 15 by centrifugal force, and when the rotary movement of the shade roller is checked by holding the window shade, the sudden stopping of the latter will throw the ball inward into engagement with the polygonal portion 7 of the spring journal. By this operation the deviceis adapted to operate with .the window shade in a horizontal, vertical or inclined position, which will be found advantageous in photograph galleries and various other places.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

lv The combination of a spring actuated shade roller provided with a spring journal having an intermediate polygonal portion and provided at the inner and outer faces thereof with rounded bearing portions, a clutch cas ing having a central bearing opening to receive the inner bearing portion of the spring journal and provided with an enlarged central opening and having an angularly disposed recess communicating therewith, a hall operating in the recess of the clutch casing and arranged to engage the polygonal portion of the spring journal, and a metallic cap receiving the clutch casing and connecting the same with the shade roller, said cap being provided at its outer end with a bearing opening fitting the outer hearing portion of the spring journal.

2. The combination with a spring actuated shade roller having a spring journal, of a clutch casing having a cen tral opening to receive the spring journal and provided with an exterior transverse groove, means carried by the clutch casing for engaging the spring journal, and a metallic cap fitting over the clutch casing and the adjacent end of the shade roller and exteriorly grooved or depressed to engage the groove of the clutch casing.

3. The combination with a spring actuated shade roller provided with a spring journal, of a clutch casing having a central opening to receive the spring journal and pro vided at its periphery with transverse grooves, means carried by the clutch casing for engaging the spring journal, and a metallic cap fitting over the clutch casing and ex- 1() teriorly grooved to engage the grooves of the said clutch casing, the grooved portions of the metallic cap being extended beyond the casing and engaging the shade roller In testimony, that I claim the foregoing as my own, I have hereto alfixed my signature in the presence of two witnesses.
